This report shows environmental, demographic, and EJ indicator values. It shows environmental and demographic raw data (e.g., the estimated concentration of
ozone in the air), and also shows what percentile each raw data value represents. These percentiles provide perspective on how the selected block group or
buffer area compares to the entire state, EPA region, or nation. For example, if a given iocation is at the 95th percentile nationwide, this means that only 5
percent of the US population has a higher block group value than the average person in the location being analyzed. The years for which the data are available,
and the methods used, vary across these indicators. Important caveats and uncertainties apply to this screening-level information, so it is essential to understand
the limitations on appropriate interpretations and applications of these indicators. Please see EJSCREEN documentation for discussion of these issues before using
reports.

* The National-Scale Air Toxics Assessment (NATA) is EPA's ongoing, comprehensive evaluation of air toxics in the United States. EPA developed the NATA to
prioritize air toxics, emission sources, and locations of interest for further study. It is important to remember that NATA provides broad estimates of health risks
over geographic areas of the country, not definitive risks to specific individuals or locations. More information on the NATA analysis can be found
at: http://www.epa.gov/ttn/atw/natamain/index.html.

EJSCREEN is a screening tool for pre-decisiona! use oniy. it can heip identify areas that may warrant additional consideration, analysis, or outreach. It does not
provide a basis for decision-making, but it may heip identify potential areas of EJ concern. Users should keep in mind that screening tools are subject to substantial
uncertainty in their demographic and environmental data, particularly when looking at small geographic areas. Important caveats and uncertainties apply to this
screening-level information, so it is essential to understand the limitations on appropriate interpretations and applications of these indicators. Please see
EJSCREEN documentation for discussion of these issues before using reports. This screening tool does not provide data on every environmental impact and
demographic factor that may be relevant to a particular location. EJSCREEN outputs should be supplemented with additional information and local knowledge
before taking any action to address potential EJ concerns.
